TREE (Total Recyclability & Efficiency Evaluation) is a visual representation of the ‘cradle to grave’ use of a product’s component materials. Winner of a D&AD Global Student Award 2007.

Comparison to the nutrient cycle
TREE is a visual representation of the ‘Cradle to grave’ use of a product’s component materials. It is inspired by the ideal cycle of nutrients in nature, where nutrients are used, broken down and re-used without loss.
Computer generated
Because of the TREE’s simplicity it could be automatically generated by a computer. All that would be required is for the product manufacturer and local refuge collection department to input information about the materials that go into the product, how long the product is expected to last, what parts would be recycled and how likely it was to be recycled.
Dependent on location
What happens to materials depends not only on the creation of the product, but also on how the product is disposed of and the capability of the consumers’ local recycling and handling of the materials. This means that the TREE process will be effected by the location of the consumer and therefore will have to be redrawn for each area. A computer-generated TREE would allow for these quick alterations for the appropriate area.
Interpreting the TREE
TREE has been designed so it can be interpreted on three levels. At a quick glance you should be able to tell which products are better in terms of material usage. At closer inspection you will be able to tell what proportion of materials a product is made up from, which materials travel the furthest, how much waste is produced while manufacturing the the product, how long the product lasts and how much of what material can be re-used. A detailed look will reveal more of the issues associated with the product and show the exact amounts of materials put into the product and the amounts wasted.
